RS-422/485 Repeaters

RS-422/RS-485 repeaters overcome the limitations of standard serial ports by using differential voltage lines for data and control signals. RS-422 and RS-485 repeaters simply amplify, or boost, existing RS-422/RS-485 signals to enable them to cover longer distances. They extend the communication distance by 1200m (4,000 ft.) and increases the maximum number of connected nodes by 32.
